U.S. Customs and Border Protection is investigating allegations an agent sexually harassed the mother of a migrant child held at the Clint Border Patrol Station.

An agent working at the Clint station allegedly sought out the undocumented mother of a Guatemalan boy, sent her Facebook messages and asked her to watch him masturbate on live video, the Washington Post reported.

"US. Customs and Border Protection is aware and is investigating this matter, but cannot comment on an ongoing investigation," a CBP spokesperson said Thursday.

"The vast majority of CBP employees are dedicated, honest, compassionate and fair professionals," the spokesperson said. "This alleged conduct is not in line with our code of conduct and will not be tolerated."

The Washington Post obtained a copy of a complaint filed with CBP and interviewed the mother, who is in California.

The woman's 12-year-old son was in custody at the Clint station after crossing the border in April in attempt to reunite with her in California, the Post reported.

During a phone call with her son, the agent first spoke with the woman before he suggested they later speak on video chat on Facebook Messenger that he used to contact her leading to the alleged sexual misconduct, the Post reported.

Neither the agent or the woman is named in the report. CBP did not disclose if he was still on duty.
